Our Fernco Couplings range covers the flexible rubber couplings, adaptor couplings, elbows, tees, end caps and bushes made by Fernco, the company formerly known as Flexseal. They join soil, waste and drain pipe of the same or different materials, such as plastic to cast iron, clay or copper, without solvent cement.

Fernco size every coupling by the outside diameter of the pipe, so each code covers a range, for example 30mm to 35mm or 76mm to 85mm. Measure the outside of both pipes and pick the coupling whose range takes them. Plumbing couplings and PlumbQwik suit waste and soil pipe above ground, while drain, shear banded, adaptor and chemical couplings suit underground drainage up to large diameters. Each listing shows the Fernco code for every size.
